Researchers from the University of Toronto analysed over 40 studies focusing on the body mass index (BMI) of both children and adults who consumed fruit juice for at least two weeks.
The findings revealed that children who drank at least 250ml of fruit juice daily experienced an average BMI increase of 0.03.
The researchers said that, “Our review and analysis of cohort studies in children showed a positive association between consuming 100% fruit juice and changes in BMI.”
“Younger children exhibited higher BMI with each additional serving per day compared to older children.”
On average, a 325ml of orange juice contains about eight-and-a-half teaspoons of sugar, while a can of Coke has nine-and-a-half teaspoons.
The researchers concluded, “Our findings support the recommendation to limit fruit juice consumption to prevent excessive calorie intake and weight gain.”
Better Health Victoria advises against all sugar-sweetened drinks for children, as they reduce diet quality, contribute to weight gain and poor oral health, and promote the habit of consuming sugary beverages.
